And it bugs me a little, but apparently not enough that I've actually done something about it.
You're viewing a single thread.
I have filled many tires with air over my life and only found out recently that you don't fill them to the pressure listed on the tire, you look for a sticker on the driver door that tells you the pressure required for the tires. The front may be different from the back. Blew my mind and I felt like all my knowledge was questionable.
Yep - like an AWD version of a car may use different pressures than a FWD version, to manage traction.
I've seen an AWD version use lower pressures in the rear than FWD - this helps keep the rear of that car from sliding due to a combination of torque transferring to the rear wheels and more weight back there.
It used to be that way with old bias ply tires and still is with trailer tires, unless otherwise stated somewhere else.
